Application led April 28, 1919. Serial No. 292,926.

To all ywho-m t may concern:

Be it known that I, ERNST HJALMAR NVA- Lonni VVEIBULL, subject of the King of Sweden, residing at Gottenborg, in the county of Gottenborg and Bohus and Kingdom or' Sweden, hai'e invented certain new and useful Improvements in or Relatingto Roller- Bea-rings, of which the following is a specific-ation.

t It is known that in roller-bearings with the rollers in the shape of spheres with two opposite sides out away or as solids of revolution of .approximately similar shape, the' rollers may be inserted .into the bearings without the provision of special filling-openings, providedlthe rollers be proportioned in a certain relation to the dimensions of the bearing. Such a proceeding may. be einployed in the case of single-row bearings by placing the outerand inner-rings of the bearing eccentrically to each other while inserting the rollers, even in case the bearingrings are provided with race-ways.

The same proceeding may also be employed in the case of multiple-row rollerbearingswith similar rollers, provided the roller-races are so farlapart from each other, that the rollers can be inserted by being turned about at right angles to their normal operative position and afterward can be turned-back again into said normal position Without any impediment from the rollers in the adjacent roller-race.

It on the contrary the roller-races are so close to each other, that the turning opera-- tion just described cannot be executed,with out causing a roller in one race to foul a roller inthe adjacentA race, the above mentioned method of insertingthe rollersI evidently cannot be adapted.

The present invention refers to a method of .inserting the rollers in a double-row `roller-bearing Without need of any fillinging-rings, Then the rollers in the other race are inserted, also turned at-900 to their ordinary operative position, and pushed" closely together along the one haltl or' the circumference of their race-way. Then the rollers are turned about in pairs, one roller in each race-way, so that they come into their ordinary operative position, and are atterward slid along the race-ways at equal distances, on the still unoccupied portion ot' the interspace between thelbearing-rings, until every roller has become thus turned around and moved into its proper place.

The annexed drawing shows, in a diagrammatical way-how the above-named procedure is performed, viz:

Figure l illustrates va side View of a donble-row roller-bearing with its'disk-shaped rollersinserted into the two race-ways in two diametrically opposite groups.

F ig'. '2 shows a .cross-section of the same roller-bearing with its rollers inserted in the above-mentioned transverse position.

Fig. 3 show-s a cross-section of the same roller-bearing with its roller inserted and turned into their ordinary operative position.

The inner-ring of the bearing is denoted by l, its two race-ways by-2 and 3. The outer-ring is denoted by -L, its race-ways by 5 and 6. Therollers are marked 7 in one otl the race-ways and 8 in the other.

The method of insertion allows of arranging; the race/ ways in such close proximity to each other, that the rollers 7 in the 'one race-way come so near to the rollers 8 in the adjacent race-way, as to prevent'the rollers from turning-about out of their normal operative position. Such a turning motion would bring the rollers in the one raceway into collision' with the rollers in the other race-way; consequently all the rollers are kept in their normal position without special roller-cages being employed.

/ This procedure.. may be adapted in connection with the employment of rollers haveaolrlwicfe; severally into their normally operative positions and moving them along the raceways at equal distances `on therunoceupied portions of the interspaoebetWeen'thei-an bearing-rings.

In testimony'- whereof -hmfeaixed my i signature in the'presence of two Witnesses.
